The diagnostic port of Peugeot 308 is located behind the trim panel under the left side of the steering wheel. This model is a 4-door, 5-seater sedan with the following dimensions: length 4590mm, width 1820mm, height 1488mm, wheelbase 2675mm, trunk capacity 450l, and curb weight 1320kg. The Peugeot 308 features MacPherson strut front suspension and torsion beam rear suspension. It is equipped with a 1.2L turbocharged engine delivering maximum power of 116PS (85kW) and maximum torque of 190Nm.
As an automotive technician, I frequently encounter questions about the diagnostic port location on the Peugeot 308. Generally, you can find it above the footwell on the driver's side beneath the steering wheel. Look down toward the knee area for a rectangular interface covered by a plastic flap - lifting this reveals the OBD-II port. This positioning is designed for convenient connection of diagnostic equipment, such as plugging in a scanner to read fault codes or monitor engine data. The location varies slightly across model years: pre-2012 versions may have a more concealed placement behind the instrument cluster, while post-2020 models relocated to more accessible positions. If you can't locate it, don't panic - check near the fuse box or consult the owner's manual for diagram references. Always turn off the ignition before operation to prevent short-circuit damage. I recommend keeping a portable OBD tool for regular self-checks, allowing quick troubleshooting when warning lights illuminate to prevent minor issues from escalating into major repairs. Keeping the interface clean and protected from moisture is crucial - maintain dryness to prolong its lifespan.
Last time my Peugeot 308's engine light came on, I wanted to troubleshoot it myself so I looked for the diagnostic port. Bending down from the driver's seat, I felt a square connector positioned a bit tightly near the lower steering column above the carpet. Just pry open the plastic cover to plug in the scanner. I found this location standard and user-friendly – connecting a Bluetooth OBD adapter to a phone app allows viewing real-time fuel consumption and emission data, which is super convenient. If you've replaced filters without clearing codes, it might trigger false alarms; using this to reset saves both hassle and money. I recommend getting a soft dust cover to protect the port from dust accumulation or accidental impacts that could affect proper contact. The interface position has been slightly adjusted in newer 308 models but remains roughly in the same area – trying a few times will help memorize it.
